Hey, last fall I had the dealership replace my idler pulley because it had a squeaky bearing. It has the 12month/12k warranty deal and since then I have put on a bassani x-pipe without cats. Just wondering what you people thought. Will they complain about the pipe? I have mil's properly installed and working so there is no check engine light. I don't think they will need to put the car on the lift for this fix. Hopefully they don't look under my car =) Anybody with and o/r pipe and mils ever have problems with shops?
